The Big Lie

Also Known As: The Grande Menzogna Colossal Untruth Strategy
Manipulation & Propaganda ID: big_lie

Definition

The Big Lie is a propaganda technique where a falsehood so enormous and audacious is asserted that people struggle to believe anyone would fabricate something so significant. The sheer scale of the claim serves as its own form of evidence — the reasoning being that no one would dare make such a claim unless it were true. The technique relies on bold, confident repetition and the exploitation of people's difficulty in comprehending deliberate large-scale deception.

Examples

Despite all official counts, court rulings, and audits confirming the results, a political leader insists: 'The entire election was stolen. Millions of fraudulent votes were cast. This was the greatest crime in our nation's history. Everyone knows it, and the evidence is overwhelming — they just won't show it to you.'

A demagogue tells his followers that a neighboring country has secretly been poisoning the water supply of border towns for decades, presenting no credible evidence. The claim is so extreme that many citizens assume there must be something to it — 'Why would anyone make up something that specific?'

A viral social media account claims that a popular children's vaccine program is actually a government operation to implant tracking microchips, and that thousands of doctors are in on it. The sheer scale of the alleged conspiracy makes some people reason that such a massive operation couldn't be entirely fabricated.

Verification Steps
Verification Steps
Binary yes/no questions that an AI must answer to detect a reasoning pattern in a text.
Each of the 452 aspects has verification steps — simple yes/no questions designed to systematically detect whether a pattern appears in a text. For ad hominem: "Does the argument attack a person rather than their claim?" For false dichotomy: "Are only two options presented when more exist?" This ensures consistent, reproducible analysis.

Binary (yes/no) questions an LLM must answer to identify this aspect:

  1. 1

    Does the claim make an extraordinarily large or dramatic assertion?

    Type: binary
  2. 2

    Is the claim repeated frequently and with confidence despite lacking credible evidence?

    Type: binary
  3. 3

    Does the scale of the claim itself seem to serve as its own justification?

    Type: binary
